- the blade driving unit 130 and the inner container driving unit 220 may be controlled by an electrically connected controller (not illustrated).
- the mixing object may continuously rotate in only one direction in the mixer container, and the mixing object may be maintained like a wall while being pushed toward the inner side surface of the mixer container, and may not retract to the pulverizing blade, such that pulverizing performance may significantly deteriorate.
- a protrusion may be formed on the inner wall of the mixer container such that a certain amount of vortex may be formed in the mixing object, and the vortex may also be implemented as a flow with a regular pattern, such that the mixing object may not be properly pulverized.

Accordingly, the mixing object may not be stacked up like a wall on the inner side surface of the inner container 210, and may return to the pulverizing blade 120 rotating in the center of the inner container 210, such that the pulverizing performance may significantly increase.
- the mixer according to the present disclosure may be configured to break the balanced state of the mixing object, such that the mixing object maintained like a wall on the inner side of the inner container 210 may collapse, thereby increasing pulverizing performance for the mixing object.
- the mixing object may move to the inner side surface of the inner container 210 by the centrifugal force by rotation of the pulverizing blade 120 while being mixed, and in this case, when the balance of the force between the particles of the mixing object is formed, the mixing object may stop and may not move any more, and the mixing object may not move toward the pulverizing blade 120 and may be no longer pulverized.

That is, the inner container 210 may be a lower component of the lateral opening 210a, and the liquid accommodation projection 210b may be formed on the lower side of the side portion preferably, which may increase the mixing effect when a certain amount of liquid (as an example, separately supplied water or the juice created from the mixing object when pulverizing the mixing object) is present when the mixing object is mixed.
- a certain amount of liquid as an example, separately supplied water or the juice created from the mixing object when pulverizing the mixing object
- the inner container 210 may rotate at a much faster speed when dewatering the mixing object than when pulverizing, such that the mixing object, which has already been pulverized in the pulverizing process, may easily move upwardly along the inner side surface of the liquid accommodation projection 210b and may rise to the lateral opening 210a, which is the upper side of the liquid accommodation projection 210b, and the juice may be dewatered through the dewatering hole 510a of the dewatering container 510 blocking the lateral opening 210a.
- the liquid accommodation projection 210b may have a height between 20% and 50% of the height of the inner container 210, and when the height is lower than 20% of the height of the inner container 210, the amount of liquid may be small, such that it may not be sufficient to enhance the mixing effect.
- the juice generated from the mixing object may not exceed the liquid accommodation projection 210b and may not reach the dewatering container 51, such that the dewatering action may be rarely performed.
- the dewatering unit 500 having the inner container 210 and the dewatering container 510 may, as the inner container 210 and the dewatering container 510 rotate together in the same direction, dewater the mixing object pulverized by the pulverizing blade 120.
- the mixing object may have a blocking component than the dewatering hole 510a of the dewatering container 510 depending on the type of the object, such that the mixing object may block the dewatering hole 510a of the dewatering container 510, and the action of dewatering the mixing object may no longer be performed.
- the mixing object may have particles larger than the dewatering hole 510a of the dewatering container 510 even when the seeds are pulverized by the pulverizing blade 120, or even when the seeds are not included, lumps having considerable viscosity may be present even after the mixing object is pulverized by the pulverizing blade 120, and accordingly, the seeds or lumps having viscosity may not pass through the dewatering hole 510a of the dewatering container 510 and may block the dewatering hole 510a, such that the dewatering action through the dewatering hole 510a of the dewatering container 510 may not be smoothly performed.
- a component of the mixing object blocking the dewatering hole 510a during the dewatering process such as a seed or viscous lumps, will be referred to as a blocking component of the mixing object.
- a scraper 214 is formed on the outer side surface of the inner container 210 in the present disclosure.

Description
- The present disclosure relates to a mixer and a dewatering method thereof, and more particularly, a mixer which may produce juice by pulverizing and dewatering a mixing object while blending the mixing object, and a dewatering method thereof.
- As for general mixers, even when a mixing object is pulverized by a pulverizing blade, a blocking component may be larger than a dewatering hole of a dewatering container, such that the component may block the dewatering hole of the rotating dewatering container, and accordingly, the dewatering action of the mixing object may be performed no more, which may be a limitation.
- That is, in the case the mixing object has a seed, even when the seed is pulverized by the pulverizing blade, the particles thereof may be larger than the dewatering hole of the dewatering container, or even when a seed is not included, lumps having considerable viscosity may be formed, even after the mixing object is pulverized by the pulverizing blade. Accordingly, the seed or viscous lumps may not pass through the dewatering hole of the dewatering container and may block the dewatering hole. Thus, in a general mixer, the dewatering action may not be swiftly carried out through the dewatering hole of the dewatering container, which may be a problem.

FIGS. 6 and7 are schematic diagrams illustrating a cross-sectional surface of a mixer according to an example embodiment. - Referring to the drawings, the mixer according to the present disclosure may include a
mixer body 100, aninner container unit 200, and adewatering unit 500. - Here, the
mixer body 100 may include anouter container 110, a pulverizingblade 120 and ablade driving unit 130. - Specifically, the
outer container 110 may include theinner container 210 of theinner container unit 200 therein, and may have an upwardly open structure in which an upper portion thereof is open. - Also, the
outer container 110 may be supported by acontainer support case 300, and thecontainer support case 300 may have an L-shape overall, as illustrated in the drawings. In this case, amixer cover 140 covering theouter container 110 may be rotatably installed in thecontainer support case 300. - Also, the
outer container 110 may have adischarge tube 112 formed in a lower portion such that the juice dewatered from a mixing object may be discharged to the outside, and an opening/closing valve 112a may be mounted on thedischarge tube 112. - The pulverizing
blade 120 may be disposed within theouter container 110, and may be configured to pulverize the mixing object in theouter container 110 while rotating. In this case, the mixing object may refer to food to be pulverized by operating the mixer. - Also, the
blade driving unit 130 may be configured to provide driving force for rotating the pulverizingblade 120, and may include ablade rotating shaft 131 and a blade driving motor M1. - The blade rotating
shaft 131 may be connected to the lower portion of the pulverizingblade 120 in the vertical direction, and the blade driving motor M1 may be connected to theblade rotating shaft 131. - That is, the
blade rotating shaft 131 may be connected to a center of the pulverizingblade 120 and may extend in the longitudinal direction, and by connecting the pulverizingblade 120 to the blade driving motor M1, the rotation driving force of the blade driving motor M1 may be transferred to the pulverizingblade 120 such that the pulverizingblade 120 may be driven to rotate when the blade driving motor M1 operates. - In this case, the
blade rotating shaft 131 and the blade driving motor M1 may be connected to each other via a first timing belt T1. - Meanwhile, the
inner container unit 200 may include aninner container 210 and an innercontainer driving unit 220. - Here, the
inner container 210 may be disposed within theouter container 110, the pulverizingblade 120 may be disposed therein, and theinner container 210 may have an upwardly open structure in which an upper portion is open, and theblade driving unit 130 may penetrate a lower portion of theinner container 210. - Also, the
inner container 210 may include aprotrusion 211 on an inner side surface such that the mixing object rotating and flowing while being pulverized by the pulverizingblade 120 may be caught by the protrusion. - Also, the inner
container driving unit 220 may be connected to theinner container 210 and may be configured to rotate theinner container 210, and the innercontainer driving unit 220 may be provided separately from theblade driving unit 130 for rotating the pulverizingblade 120. - Specifically, the inner
container driving unit 220 may include an inner container rotating shaft 222 and an inner container driving motor M2. - Here, the inner container rotating shaft 222 may be connected to the lower portion of the
inner container 210 in the vertical direction, and the inner container driving motor M2 may be connected to the inner container rotating shaft 222. - That is, the inner container rotating shaft 222 may be connected to the lower portion of the
inner container 210 and may extend in the longitudinal direction, by connecting theinner container 210 to the inner container driving motor M2, the rotation driving force of the inner container driving motor M2 may be transferred to theinner container 210 such that theinner container 210 may be driven to rotate when the inner container driving motor M2 operates. - In this case, the inner container rotating shaft 222 and the inner container driving motor M2 may be connected to each other via a second timing belt T2.
- The
blade driving unit 130 and the innercontainer driving unit 220 may be controlled by an electrically connected controller (not illustrated). - Meanwhile, in a general mixer, as the pulverizing blade rotates in only one direction, the mixing object may continuously rotate in only one direction in the mixer container, and the mixing object may be maintained like a wall while being pushed toward the inner side surface of the mixer container, and may not retract to the pulverizing blade, such that pulverizing performance may significantly deteriorate.
- In a general mixer, a protrusion may be formed on the inner wall of the mixer container such that a certain amount of vortex may be formed in the mixing object, and the vortex may also be implemented as a flow with a regular pattern, such that the mixing object may not be properly pulverized.
- Accordingly, in the mixer according to the present disclosure, the controller may control the inner
container driving unit 220 to mix the mixing object while varying rotation of theinner container 210 to implement an irregular flow in the mixing object of theinner container 210. - As an example embodiment, the controller may control the
blade driving unit 130 and the innercontainer driving unit 220 such that thepulverizing blade 120 and theinner container 210 may rotate in opposite directions. - In this case, the controller may repeatedly turn the power of the inner
container driving unit 220 on and off, and when the power is turned off, theinner container 210 may rotate forwards on inertia without power, and may be interlocked with rotational force of the mixing object by thepulverizing blade 120 and may rotate in reverse. - That is, the controller may control the
blade driving unit 130 and the innercontainer driving unit 220, such that, while thepulverizing blade 120 and theinner container 210 may rotate in opposite directions, the innercontainer driving unit 220 may be repeatedly controlled to be turned on and off, and accordingly, when the power of the innercontainer driving unit 220 is turned on, theinner container 210 may in reverse rotate (rotating in the direction opposite to the pulverizing blade 120), and when the power of the innercontainer driving unit 220 is turned off, theinner container 210 may rotate forwards on inertia without power, the rotational speed may decrease, and theinner container 210 may rotate forwards (rotating in the same direction as the pulverizing blade 120) by the rotational force of the mixing object by thepulverizing blade 120. - In other words, the
inner container 210 may receive the driving force from the innercontainer driving unit 220 only when the controller turns on the power of the innercontainer driving unit 220, and when the controller turns off the power of the innercontainer driving unit 220, theinner container 210 may not receive the driving force from the innercontainer driving unit 220 such that theinner container 210 may rotate on inertia and may rotate forwards by being interlocked with the rotational force of the mixing object. - Particularly, to break the balanced state of the mixing object in the
inner container 210, the controller may control the innercontainer driving unit 220 such that theinner container 210 may mix the mixing object while repeating the pattern in which theinner container 210 may rotate in reverse and stop in the direction opposite to the rotation direction of thepulverizing blade 120, or the pattern in which theinner container 210 may rotate in reverse and may change speed. - As another example embodiment, the inner
container driving unit 220 may include a DC motor and a switch circuit, or may include an AC motor and an inverter, such that theinner container 210 may rotate forwards and in reverse by the driving force of the innercontainer driving unit 220 under the control of the controller. - That is, as the switch circuit or the inverter of the inner
container driving unit 220 is used, theinner container 210 may be driven to rotate by receiving the driving force from the innercontainer driving unit 220 when theinner container 210 rotates in reverse and also rotate forwards under the control of the controller. - As described above, in the mixer according to the present disclosure, as the inner
container driving unit 220 is controlled to mix the mixing object while varying the rotation direction of theinner container 210 by the controller, and particularly, as the variation of rotation of theinner container 210 in which the innercontainer driving unit 220 is repeatedly turned on and off such that theinner container 210 may rotate in reverse for a predetermined period of time and stop and may rotate in reverse for a predetermined period of time and stop again by the controller is implemented, the balanced state of the mixing object may be broken. Accordingly, the mixing object may not be stacked up like a wall on the inner side surface of theinner container 210, and may return to thepulverizing blade 120 rotating in the center of theinner container 210, such that the pulverizing performance may significantly increase. - That is, the mixer according to the present disclosure may be configured to break the balanced state of the mixing object, such that the mixing object maintained like a wall on the inner side of the
inner container 210 may collapse, thereby increasing pulverizing performance for the mixing object. - Specifically, the mixing object may move to the inner side surface of the
inner container 210 by the centrifugal force by rotation of thepulverizing blade 120 while being mixed, and in this case, when the balance of the force between the particles of the mixing object is formed, the mixing object may stop and may not move any more, and the mixing object may not move toward thepulverizing blade 120 and may be no longer pulverized. - In the mixer according to the present disclosure, however, as the pattern in which the rotation direction of the
inner container 210 changes or theinner container 210 rotates in reverse and stops, or the pattern in which theinner container 210 rotates in reverse and changes the speed thereof is repeated, the balance of the force between the particles of the mixing object may change to an unbalanced state. Accordingly, the particles may flow again and may move to move toward thepulverizing blade 120 while flowing, such that the pulverizing may be continuously performed. - Also, in the mixer according to the present disclosure, when the
blade driving unit 130 and the innercontainer driving unit 220 rotate thepulverizing blade 120 and theinner container 210 in opposite directions, or particularly, the pattern in which theinner container 210 rotates in reverse and stops or the pattern in which theinner container 210 rotates in reverse and changes the speed thereof is repeated, the effect of pulverizing the mixing object may further increase by the shape structure of theprotrusion 211. - Specifically, the
protrusion 211 may have the shape of a screw protrusion line guiding a downward spiral flow of the mixing object such that the mixing object may flow downwardly while rotating in the opposite direction to the rotation of thepulverizing blade 120. - Specifically, as for the flow of the mixing object rotating in one direction by the
pulverizing blade 120, as thepulverizing blade 120 is disposed on the lower side in theinner container 210, while thepulverizing blade 120 rotates, thepulverizing blade 120 may be pushed up to the inner side of theinner container 210 and may rise upwardly along the inner side surface of theinner container 210. Accordingly, the mixing object flowing upwardly while receiving the centrifugal force as described above may minimally flow toward thepulverizing blade 120 disposed on the lower side in theinner container 210. - Accordingly, to allow the mixing object flowing as above to flow toward the
pulverizing blade 120 disposed on the lower side in theinner container 210, when thepulverizing blade 120 and theinner container 210 rotate in opposite directions, theprotrusion 211 may have the shape of a screw protrusion line to allow the mixing object to flow downwardly while rotating in the opposite direction to the direction of rotation of thepulverizing blade 120, thereby guiding the downward spiral flow of the mixing object. - That is, the mixing object, which may come into contact with the inner side surface of the inner container while rotating in one direction, may collide with the screw protruding line rotating in the opposite direction and may move downwardly along the spiral structure of the screw protruding line, such that the mixing object may flow toward the
pulverizing blade 120 disposed on the lower side in theinner container 210, thereby increasing the pulverizing effect of the mixer. - Meanwhile, the
dewatering unit 500 may be configured to dewater the pulverized mixing object after the mixing object is pulverized by thepulverizing blade 120, that is, to separate the juice from the mixing object. - Here, the
dewatering unit 500 may include adewatering container 510. - In this case, the
inner container 210 may include alateral opening 210a on the side surface thereof such that the inner and outer portions are connected to each other, thedewatering container 510 may be configured to block thelateral opening 210a of theinner container 210, and adewatering hole 510a may be formed on the side portion. - That is, the
dewatering container 510 may have the structure of blocking thelateral opening 210a by surrounding theinner container 210, such that the mixing object accommodated in theinner container 210 may be prevented from coming out of theinner container 210 through thelateral opening 210a of theinner container 210. - Specifically, the
lateral opening 210a may be disposed at a predetermined height from the side portion of theinner container 210. That is, theinner container 210 may be a lower component of thelateral opening 210a, and theliquid accommodation projection 210b may be formed on the lower side of the side portion preferably, which may increase the mixing effect when a certain amount of liquid (as an example, separately supplied water or the juice created from the mixing object when pulverizing the mixing object) is present when the mixing object is mixed. - Even when the
liquid accommodation projection 210b is formed on the lower side of the side portion of theinner container 210, theinner container 210 may rotate at a much faster speed when dewatering the mixing object than when pulverizing, such that the mixing object, which has already been pulverized in the pulverizing process, may easily move upwardly along the inner side surface of theliquid accommodation projection 210b and may rise to thelateral opening 210a, which is the upper side of theliquid accommodation projection 210b, and the juice may be dewatered through thedewatering hole 510a of thedewatering container 510 blocking thelateral opening 210a. - As an example, the
liquid accommodation projection 210b may have a height between 20% and 50% of the height of theinner container 210, and when the height is lower than 20% of the height of theinner container 210, the amount of liquid may be small, such that it may not be sufficient to enhance the mixing effect. When the height is greater than 50% of the height of theinner container 210, the juice generated from the mixing object may not exceed theliquid accommodation projection 210b and may not reach the dewatering container 51, such that the dewatering action may be rarely performed. - The
dewatering unit 500 having theinner container 210 and thedewatering container 510 may, as theinner container 210 and thedewatering container 510 rotate together in the same direction, dewater the mixing object pulverized by thepulverizing blade 120. - However, even when the mixing object is pulverized by the
pulverizing blade 120, the mixing object may have a blocking component than thedewatering hole 510a of thedewatering container 510 depending on the type of the object, such that the mixing object may block thedewatering hole 510a of thedewatering container 510, and the action of dewatering the mixing object may no longer be performed. - That is, when the seeds are included in the mixing object, the mixing object may have particles larger than the
dewatering hole 510a of thedewatering container 510 even when the seeds are pulverized by thepulverizing blade 120, or even when the seeds are not included, lumps having considerable viscosity may be present even after the mixing object is pulverized by thepulverizing blade 120, and accordingly, the seeds or lumps having viscosity may not pass through thedewatering hole 510a of thedewatering container 510 and may block thedewatering hole 510a, such that the dewatering action through thedewatering hole 510a of thedewatering container 510 may not be smoothly performed. - For reference, in this present disclosure, a component of the mixing object blocking the
dewatering hole 510a during the dewatering process, such as a seed or viscous lumps, will be referred to as a blocking component of the mixing object. - To address the above-described issue, a
scraper 214 is formed on the outer side surface of theinner container 210 in the present disclosure. - The
scraper 214 protrudes from the outer side surface of theinner container 210, and when there is a difference in the rotational speeds between theinner container 210 and thedewatering container 510, thescraper 214 scrapes off the blocking component of the mixing object blocking thedewatering hole 510a of thedewatering container 510. - That is, the
scraper 214 of theinner container 210 may scrape off the blocking component of the mixing object protruding from the inner side surface of thedewatering container 510 while blocking thedewatering hole 510a of thedewatering container 510 from the inner side surface of thedewatering container 510 when there is a difference in the rotational speeds between theinner container 210 and thedewatering container 510. - Specifically, the
scraper 214 may be formed in the longitudinal direction from the outer side surface of theinner container 210, and may be configured to protrude to the inner side surface of thedewatering container 510. Thescraper 214 may scrape off the mixing object present in thedewatering hole 510a of thedewatering container 510 or attached to the inner side surface of thedewatering container 510 from the entire portion of thedewatering container 510 by the above-described structure. - Furthermore, a plurality of the
lateral openings 210a may be formed in the transverse direction from the side portion of theinner container 210, thereby increasing the dewatering performance for the mixing object. - Also, a plurality of the
scrapers 214 may be disposed between the plurality oflateral openings 210a, such that, even when the difference in speeds between theinner container 210 and thedewatering container 510 is maintained for a relatively short period of time, thescrapers 214 may scrape off the blocking component from the entire portion of thedewatering container 510, and also, the blocking components of the mixing object not being easily separated may be properly scraped off as thescrapers 214 scrape the component off several times while rotating. - Also, to obtain the structure in which the
dewatering container 510 may block thelateral opening 210a of theinner container 210 such that the mixing object may not be discharged through thelateral opening 210a, as illustrated inFIG. 10 , the protrusion height of thescraper 214 protruding from the outer side surface of theinner container 210 may be configured to be lower than the protrusion height of theprotrusion 211 protruding from the inner side surface of theinner container 210, and may have a protrusion height protruding slightly preferably. - Meanwhile, in the present disclosure, to generate a difference in rotational speeds between the
inner container 210 and thedewatering container 510, as illustrated inFIGS. 6 ,9 , and10 as an example embodiment, thedewatering unit 500 and thedewatering container 510 described above may each have a dewatering container speed change device. - In this case, the dewatering container speed change device may include a dewatering container
speed limiting unit 520 for limiting the rotational speed of the dewatering container. - The dewatering container
speed limiting unit 520 may be configured to limit the rotational speed of thedewatering container 510, that is, to stop or decelerate the rotation of thedewatering container 510. - Here, the rotational movement of the
dewatering container 510 will be described first. - The
dewatering container 510 may have a structure configured to block thelateral opening 210a by enclosing theinner container 210, and even when a separate rotational driving force is not provided by this structure, thedewatering container 510 may rotate together while theinner container 210 rotates. - Specifically, the mixing object rotating by the rotation of the
inner container 210 may be in contact with the inner side surface of thedewatering container 510 through thelateral opening 210a of theinner container 210, such that thedewatering container 510 may rotate in the rotation direction of the mixing object and may rotate in the same direction as theinner container 210. - The rotational speed of the
dewatering container 510 rotating as above may be limited by the dewatering containerspeed limiting unit 520, and the structure of the dewatering container speed limiting unit may be as below. - The dewatering container
speed limiting unit 520 may include astop pin 521 and apin driving member 522 as illustrated inFIGS. 6 and9 as an example. - In this case, the
dewatering container 510 may include a plurality ofstop grooves 510b along the lower edge thereof, and thestop pin 521 may rise toward thestop groove 510b of thedewatering container 510, and may stop the rotation of thedewatering container 510 by being drawn and caught into thestop groove 510b. - Also, the
pin driving member 522 may be configured to lift thestop pin 521. As an example, a solenoid container may be used, but an example embodiment thereof is not limited thereto, and any generally used driving member may be used as long as the driving member may stably lift thestop pin 521. - For reference, when the
pin driving member 522 is a solenoid container, thestop pin 521 may be a cylinder rod or a member connected to the cylinder rod. - Meanwhile, the
stop pin 521 may not be connected to thepin driving member 522 as illustrated inFIGS. 6 and9 , and as another example, thepin driving member 522 may be configured to be separated from thepin driving member 522 as illustrated inFIG. 10 . - Specifically, the
outer container 110 may include astop hole 110c in which thestop pin 521 moves up and down in the lower portion thereof, and apin accommodation bracket 111 may be formed to accommodate thestop pin 521 on the lower side of thetop hole 110c in the lower portion. - Also, the dewatering container
speed limiting unit 520 may further include anelastic member 523. - The
elastic member 523 may be disposed between the head of thestop pin 521 and the lower surface of theouter container 110, such that, when the lifting pressure of thepin driving member 522 with respect to thestop pin 521 is released, theelastic member 523 may provide elastic force to move down thestop pin 521 while the state in which thestop pin 521 blocks thestop hole 110c is maintained. - That is, when the
pin driving member 522 operates and the cylinder rod 522a raises such that the lower end of thestop pin 521, that is, the head of thestop pin 521 is pushed and raised by thebracket hole 111a, theelastic member 523 may be compressed, and thestop pin 521 may rise through thestop hole 110c of theouter container 110 and may be inserted into thestop groove 510b of thedewatering container 510, thereby stopping the rotation of thedewatering container 510. Conversely, when the cylinder rod 522a is reduced, the upward pressure on thestop pin 521 may be released, such that theelastic member 523 may expand and push the head of thestop pin 521 to move down such that thestop pin 521 may be released from thestop groove 510b of thedewatering container 510. In this case, thestop pin 521 may not completely come out from thestop hole 110c and the upper portion thereof may maintains the state of remaining in thestop hole 110c. Accordingly, the liquid dewatered from the mixing object from flowing out through thestop hole 110c of theouter container 110 may be prevented when theouter container 110 rotates and is removed from the container support case 300 (inFIG. 1 ), and further, in the vacuum mixer, operating in a vacuum, the vacuum in theouter container 110 may be prevented from being released. - For reference, to allow the
stop pin 521 to be smoothly and easily inserted into thestop groove 510b of thedewatering container 510, the controller may control the innercontainer driving unit 220 to decrease the rotational speed of theinner container 210 to a certain extent, such that the rotational speed of the mixing object may be lowered, and accordingly, thedewatering container 510 may slowly rotate while being interlocked therewith. - Also, the
dewatering unit 500 may further include a dewateringcontainer support rail 524. - The dewatering
container support rail 524 may be disposed within theouter container 110, and the lower rim of thedewatering container 510 may be seated therein and the dewateringcontainer support rail 524 may support thedewatering container 510 to slide and rotate. - The dewatering
container support rail 524 may be configured to allow thedewatering container 510 to stably rotate without shaking while thedewatering container 510 rotates, and the specific structure thereof is not limited to any particular example, and any generally used structure may be used. - The dewatering container
speed limiting unit 520 may include a friction pad and a pad driving member to reduce the rotational speed of thedewatering container 510, not illustrated in the drawings. - When the friction pad may rise to the lower side of the
dewatering container 510 and may be in contact with the lower portion of thedewatering container 510, such that the rotational speed of thedewatering container 510 may be reduced. - Also, the pad driving member may be connected to the friction pad, and may be configured to lift the friction pad. As an example, a solenoid container may be used.
- Further, in the present disclosure in which the above-described dewatering container
speed limiting unit 520 is provided, theblade rotating shaft 131 may be disposed within the hollow of the innercontainer rotating shaft 221, and theblade rotating shaft 131 and the innercontainer rotating shaft 221 may rotate independently of each other. - Specifically, a first bearing B1 may be installed between the
blade rotating shaft 131 and the innercontainer rotating shaft 221, and a second bearing B2 may be installed between thelower extension portion 113 extending from the lower portion of theouter container 110 and formed around the innercontainer rotating shaft 221 and the innercontainer rotating shaft 221. - In this case, the second bearing B2 may be a one-way bearing, and the second bearing B2 may, when the mixing object rotates in high speed by the high-speed rotation of the
blade rotating shaft 131, prevent theinner container 210, which may have to rotate in the opposite direction of theblade rotating shaft 131, from rotating in the same direction as theblade rotating shaft 131 by the mixing object rotating in high speed. - The open upper portion of the
outer container 110 may be opened and closed by theouter container cover 110a, the open upper portion of thedewatering container 510 may be opened and closed by the dewateringcontainer cover 511, and the open upper portion of theinner container 210 may be opened and closed by theinner container cover 210. - Here, an outer
container cover groove 110b may be formed on the lower surface of theouter container cover 110a, and a dewateringcontainer cover projection 511b configured to be inserted into the outercontainer cover groove 110b and to be rotatable may be formed on the upper surface of thedewatering container cover 511. - In this case, a dewatering
container cover groove 511a may be formed on the lower surface of thedewatering container cover 511, and an innercontainer cover projection 230a configured to be inserted into the dewateringcontainer cover groove 511a and to be rotatable may be formed on the upper surface of theinner container cover 210. - By the structure of the covers described above, the
inner container 210 and thedewatering container 510 may rotate stably without shaking. -
FIG. 11 is a schematic diagram illustrating a cross-sectional surface of a mixer according to another example embodiment.FIG. 12 is a schematic diagram illustrating an example in which a shaft connection member of another example embodiment. - In the present disclosure, to generate a difference in rotational speeds between the
inner container 210 and thedewatering container 510, thedewatering unit 500 may include a dewatering container speed change device along with thedewatering container 510 described above, as illustrated inFIGS. 11 and12 as another example embodiment. - In this case, the dewatering container speed change device may include a dewatering
container driving unit 530 for driving and rotating thedewatering container 510. - The dewatering
container driving unit 530 may include a dewateringcontainer rotating shaft 531 and a dewatering container driving motor M3. - Here, the dewatering
container rotating shaft 531 may be vertically connected to the lower portion of thedewatering container 510, and the dewatering container driving motor M3 may be connected to the dewateringcontainer rotating shaft 531. - That is, the dewatering
container rotating shaft 531 may be connected to the lower portion of thedewatering container 510 and may extend in the longitudinal direction, and by connecting thedewatering container 510 to the dewatering container driving motor M3 and transferring the rotational driving force of the dewatering container driving motor M3 to thedewatering container 510, thedewatering container 510 may be driven to rotate when the dewatering container driving motor M3 operates. - In this case, the dewatering
container rotating shaft 531 and the dewatering container driving motor M3 may be connected to each other via a third timing belt T3. - Accordingly, the rotational speed and rotation direction of the
inner container 210 may change by the innercontainer driving unit 220, and the rotational speed and rotation direction of thedewatering container 510 may change by the dewateringcontainer driving unit 530, and accordingly, there may be a difference in rotational speeds between theinner container 210 and thedewatering container 510. - For reference, the inner
container driving unit 220 and the dewateringcontainer driving unit 530 may be controlled by a controller electrically connected. - Further, in the present disclosure in which the above-described dewatering
container driving unit 530 is provided, theblade rotating shaft 131 may be disposed within the hollow of the innercontainer rotating shaft 221, and the innercontainer rotating shaft 221 may be disposed within the hollow of the dewateringcontainer rotating shaft 531, such that theblade rotating shaft 131, the innercontainer rotating shaft 221, and the dewateringcontainer rotating shaft 531 may rotate independently of each other. - Specifically, a first bearing B1 may be installed between the
blade rotating shaft 131 and the innercontainer rotating shaft 221, and a second bearing B2 may be installed between the innercontainer rotating shaft 221 and the dewateringcontainer rotating shaft 531. - Also, a third bearing B3 may be installed between the
